2. Mose 22:18

Thou shalt not suffer a witch to live - If there had been no witches, such a law as this had never been made. The existence of the law, given under the direction of the Spirit of God, proves the existence of the thing. It has been doubted whether מכשפה mecash-shephah, which we translate witch, really means a person who practiced divination or sorcery by spiritual or infernal agency. Whether the persons thus denominated only pretended to have an art which had no existence, or whether they really possessed the power commonly attributed to them, are questions which it would be improper to discuss at length in a work of this kind; but that witches, wizards, those who dealt with familiar spirits, etc., are represented in the sacred writings as actually possessing a power to evoke the dead, to perform, supernatural operations, and to discover hidden or secret things by spells, charms, incantations, etc., is evident to every unprejudiced reader of the Bible. Of Manasseh it is said: He caused his children to pass through the fire in the valley of the son of Hinnom: also he observed times [ועונן, veonen, he used divination by clouds] and used enchantments, and used witchcraft, [וכשף vechishsheph], and dealt with a familiar spirit, [ועשה אוב veasah ob, performed a variety of operations by means of what was afterwards called the πνευμα πυθωνος, the spirit of Python], and with wizards, [ידעוני yiddeoni, the wise or knowing ones]; and he wrought much evil in the sight of the Lord; Ch2 33:6. It is very likely that the Hebrew כשף cashaph, and the Arabic cashafa, had originally the same meaning, to uncover, to remove a veil, to manifest, reveal, make bare or naked; and mecashefat is used to signify commerce with God. See Wilmet and Giggeius. The mecashshephah or witch, therefore, was p…

LAWS CONCERNING THEFT. (Exo. 22:1-31) If a man shall steal an ox, or a sheep--The law respects the theft of cattle which constituted the chief part of their property. The penalty for the theft of a sheep which was slain or sold, was fourfold; for an ox fivefold, because of its greater utility in labor; but, should the stolen animal have been recovered alive, a double compensation was all that was required, because it was presumable he (the thief) was not a practised adept in dishonesty. A robber breaking into a house at midnight might, in self-defense, be slain with impunity; but if he was slain after sunrise, it would be considered murder, for it was not thought likely an assault would then be made upon the lives of the occupants. In every case where a thief could not make restitution, he was sold as a slave for the usual term.

Thou shall not suffer a witch to live. Such that had familiar spirits, and conversed with them, and by means thereof got knowledge of many things relating to persons, at least pretending they did; and who did or seemed to do many strange and surprising feats, as even to raise the spirits of departed persons, to converse with them and gain knowledge by them, though in reality they did not, and could not do such things, but used some juggling tricks to deceive the people, and in which they might be assisted by evil spirits; as appears from the case of the witch of Endor, who was surprised at the appearance of Samuel, it being out of the ordinary course of her art and practice really to bring up the spirit of a man deceased, whatever pretensions might be made to it; however, such being deceivers of the people, and leading them into unwarrantable practices, and off of a dependence on God and his providence, and from seeking to him, and asking counsel of him, they are by this law condemned to death, such an one was not to be suffered to live; not that it was lawful for anybody to kill her, or that any private person might or must do it that knew her, or took her to be a witch; but she was to be had before a court of judicature and tried there, and, if found guilty, to be put to death by the civil magistrate: so Jarchi's note is,"but she shall die by the house of judgment;''or the sanhedrim; for these words are spoken to Moses the chief judge, and to those that were under him, and succeeded him and them; though the Targum of Jonathan prefaces them thus:"and my people, the children of Israel, thou shalt not, &c.''and though only a witch is mentioned, or this is only expressed in the feminine gender, because a multitude of this sort of people were found among women, as Ben Mele…

The laws which follow, from Exo 22:18 onwards, differ both in form and subject-matter from the determinations of right which we have been studying hitherto: in form, through the omission of the כּי with which the others were almost invariably introduced; in subject-matter, inasmuch as they make demands upon Israel on the ground of its election to be the holy nation of Jehovah, which go beyond the sphere of natural right, not only prohibiting every inversion of the natural order of things, but requiring the manifestation of love to the infirm and needy out of regard to Jehovah. The transition from the former series to the present one is made by the command in Exo 22:18, "Thou shalt not suffer a witch to live;" witchcraft being, on the one hand, "the vilest way of injuring a neighbour in his property, or even in his body and life" (Ranke), whilst, on the other hand, employment of powers of darkness for the purpose of injuring a neighbour was a practical denial of the divine vocation of Israel, as well as of Jehovah the Holy One of Israel. The witch is mentioned instead of the wizard, "not because witchcraft was not to be punished in the case of men, but because the female sex was more addicted to this crime" (Calovius). תחיּה לא (shalt not suffer to live) is chosen instead of the ordinary יוּמת מות (shall surely die), which is used in Lev 20:27 of wizards also, not "because the lawgiver intended that the Hebrew witch should be put to death in any case, and the foreigner only if she would not go when she was banished" (Knobel), but because every Hebrew witch was not to be put to death, but regard was to be had to the fact that witchcraft is often nothing but jugglery, and only those witches were to be put to death who would not give up their witchcraft when it was forbidde…

The laws of this chapter relate, I. To the eighth commandment, concerning theft (Exo 22:1-4), trespass by cattle (Exo 22:5), damage by fire (Exo 22:6), trusts (Exo 22:7-13), borrowing cattle (Exo 22:14, Exo 22:15), or money (Exo 22:25-27). II. To the seventh commandment. Against fornication (Exo 22:16, Exo 22:17), bestiality (Exo 22:19). III. To the first table, forbidding witchcraft (Exo 22:18), idolatry (Exo 22:20). Commanding to offer the firstfruits (Exo 22:29, Exo 22:30). IV. To the poor (Exo 22:21-24). V. To the civil government (Exo 22:28). VI. To the peculiarity of the Jewish nation (Exo 22:31).

22:18 The practices of a sorceress represented the pagan worldview from which God was delivering his people. That worldview was utterly incompatible with the biblical one (see 20:3; 23:13).
